When you set up a nursery, you're usually worried about sharp furniture corners and outlet covers. You don't expect the white noise machine to catch fire. But a new federal recall of a popular infant sleep device proves that lithium-ion batteries can pose hidden risks in our most sensitive rooms. At the same time, federal researchers are quietly working to overhaul how the rest of your home handles heat and energy.
A hidden fire risk in the baby's room
If you bought a portable sound machine recently, it's time to check the label. NBC News reports that Love to Dream recalled its portable Sleep Machine. The lithium-ion battery can overheat and cause a fire if plugged into an incompatible charger.
The affected units are easy to spot. They're white, heart-shaped devices with a built-in night light and a tan carry strap. The recall covers model number LTD-SM23, sold to consumers from February 2025 through September 2026. You can find the date code, 7W15TN, printed on the side of the sound machine or the back of the original box.
If you have this exact model, unplug it immediately. The U.S. Consumer Product Safety Commission warns against tossing it in your regular household trash or recycling bins. Damaged lithium batteries are notorious for sparking garbage truck and landfill fires. Store the device in a safe spot away from flammable materials. You can claim a full refund by visiting lovetodream.com/recall or calling 1-833-753-3710.
Making glass act like a solid wall
While you're inspecting the nursery, look at the window. Right now, even decent double-pane glass is essentially an energy leak. The Department of Energy wants to change that. They're funding research into highly insulating windows, dynamic solar control, and daylighting.
The ultimate goal is to develop windows that insulate just as well as your solid walls. These high-performance windows are designed to actively work with the seasons. They harvest passive heat when it's freezing outside and block the sun when summer hits.
Researchers hope to get the installation costs down so average homeowners can actually afford them. Better glass would dramatically lower peak electricity demand. Your house stays comfortable, and you don't have to give up natural daylight or outdoor views.
The bottom line
- If you need to replace a recalled Love to Dream unit, the Hatch Go is a solid alternative that runs for up to 15 hours per charge. For larger plug-in devices around your house, our appliances guide explains how to spot electrical risks early.
- Drafty windows force your heating and cooling equipment to work overtime. If your nursery feels chilly near the glass this week, check your weatherstripping. You can also consult our HVAC & climate control guide to make sure your system is properly balanced for the season.
